Abstract:
(EN) Provided are: a melt blown (MB) nonwoven fabric; a laminate using the same; a melt blow nonwoven fabric production method; and a melt blowing apparatus. A melt blowing apparatus 100 is provided with a die 10 for discharging a resin melt 42 together with an associated flow, a hollow cover 20, and a collection member 60. A discharged thread-like substance 50 from the die 10 is heated to at least the crystallization temperature of the thermoplastic resin inside the hollow cover 20 and is collected by a collecting surface 62 of the collection member 60. The hollow cover 20 and the collection member 60 are separated such that the distance from a lower edge 28 of the hollow cover 20 to the collecting surface 62 in a straight line in the vertically downward direction from a nozzle hole 12 is at least 5 cm.
(FR) L'invention concerne: un tissu non tissé produit par fusion-soufflage (MB); un stratifié l'utilisant; un procédé de production de tissu non tissé produit par fusion-soufflage; et un appareil de fusion-soufflage. Un appareil de fusion-soufflage 100 est pourvu d'une filière 10 pour décharger une masse fondue de résine 42 conjointement avec un écoulement associé, d'un couvercle creux 20, et d'un élément de collecte 60. Une substance filiforme 50 évacuée de la filière 10 est chauffée à au moins la température de cristallisation de la résine thermoplastique à l'intérieur du couvercle creux 20 et est collectée par une surface de collecte 62 de l'élément de collecte 60. Le couvercle creux 20 et l'élément de collecte 60 sont séparés de telle sorte que la distance entre le bord inférieur 28 du couvercle creux 20 et la surface de collecte 62 est d'au moins 5 cm en ligne droite dans la direction verticale vers le bas depuis un trou de buse 12.
(JA) メルトブローン(MB)不織布、およびそれを用いた積層体、ならびにメルトブローン不織布の製造方法およびメルトブロー装置を提供する。メルトブロー装置100は、樹脂溶融物42を随伴流とともに吐出するためのダイ10と、中空状カバー部20と、捕集部材60とを備える。ダイ10からの吐出糸状物50は、中空状カバー部20内部において前記熱可塑性樹脂の結晶化温度以上に加温され、捕集部材60の捕集面62により捕集される。中空状カバー部20と捕集部材60とは、ノズル孔12からの鉛直方向下向きの直線において、中空状カバー部20下端28から捕集面62までの距離として5cm以上離れている。
